| 1. | Oolite lime sand packs naturally with 40% porosity because the particles are essentially spheroids . 自然堆积的灰质鲕粒砂具有40的孔隙度,因为其颗粒其本上都是球状的。 |
| 2. | Characteristics of feixianguan formation oolitic shoal reservoirs in northeast sichuan basin 川东北飞仙关组鲕粒滩储层特征研究 |
| 3. | Oolitic limestones are rare and interbedded in the dark - gray mudstones and / or shales 这些砂岩和鲕粒灰岩既可单独成层,但更常见它们与深灰色泥页岩组合成薄互层。 |
| 4. | Diagenesis of oolitic bank of the feixianguan formation of lower triassic in luojiazhai gas field , northeastern sichuan province 川东北罗家寨气田下三叠统飞仙关组鲕粒滩成岩作用 |
| 5. | According to its fades sequence features , the oolitic rocks are deposited in platform marginal oolitic bar and inner - platform oolitic bank 蒸发台地西缘的台缘鲕粒坝在飞仙关期基本稳定。 |
| 6. | The feixianguan gas reservoirs in the luojiazhai gas field , northeastern sichuan province , are composed of the porous oolitic dolomites 摘要四川东北部罗家寨气田的储层为下三垒统飞仙关组孔隙性鲕粒白云岩。 |
| 7. | The primary rocks were sparry oolitic limestone and micrite oolitic limestone , but dolomitization destroyed the original sedimentary textures 原生岩石为亮晶鲕粒石灰岩和泥晶鲕粒石灰岩,白云石化作用使其岩石结构大多遭受破坏。 |
| 8. | The reservoirs mainly exist in the oolitic bank facies in the carbonate platforms , which were deposited in high energy environment and mainly controlled by tidal action 其沉积相属碳酸盐台地的鲕粒滩相,为台地潮下较高能环境沉积,主要受潮汐作用的控制。 |
| 9. | The middle part is a set of large tidal range tidal sequence including oolitic shoal fades which is made up of bedded - oolite dolomite and oolite limestone , gypsum - tidal fades in sabkha environment which consists of bedded gypsolyte , and gypsolyte - bearing gypsum - dolomite tidal facies 中部为层状鲕粒白云岩、鲕粒灰岩的潮下鲕粒滩相与萨布哈环境的富层状石膏岩的膏坪相、含石膏岩的膏云坪相组成的大潮差蒸发潮坪层序。 |
| 10. | The paper analyzed sedimentary characteristics and depositional environment in t1f3 this region firstly , and on the grounds of establishing logical deposit pattern gave emphasis to make a study of distributing laws and spreading traits of the oolitic beach . because diagenesis is a vitally dominating factor that influenced oolitic beach reservoir nature in the region , the master diagenetic events of the reservoir in the lengthy geological history , as well as the influence to the pore abundance , was made a study of . the diagenetic stages and sequences were divided and the pore evolve pattern was established in the paper 本论文首先分析了研究区飞三段的沉积特征与沉积环境,在合理建立沉积相模式的基础上重点研究了鲕粒滩(坝)的分布规律和空间展布特点;成岩作用是影响本区鲕滩储集性至关重要的控制因素,论文详细研究了储层在漫长地质历史过程中所经历的主要成岩事件及其对孔隙发育的影响,划分了成岩阶段与成岩演化次序,建立了孔隙演化模式并以建南构造为例进行了成岩相展布研究的尝试;最后还在鲕滩储层基本特征研究的基础上对飞三段储层进行综合评价与预测。 |
